Windows 7: 32 bit vs 64 bit Comparison

Hi,

You cannot upgrade 32bit to 64 bit, so you need to completely reinstall 64 bit Windows. Simply insert your Windows DVD, and then install again from scratch, overwriting the previous installation.

Be sure to backup any of your critical files that you would like to keep before doing this.

Regards,
Golden

Any help you can give this babe will be much appreciated,thanks.
As golden said, you cannot upgrade over it, but you can install over it just like normal. No need to do anything special to remove the x32 OS first, just make sure you backup anything you want to keep.

A bit is the basic computer data and is a one or zero. 8 bits make a byte or one character such as a letter or symbol. The CPU addresses data on the bit level and moves it between the hard drive, memory, CPU and back. In a 32 bit system, also called X86, it will move data in a line or stream of data which is 32 bits wide. The 64 bit, X64, will move data 64 bits at a time, or twice as fast.
Software must be designed to take advantage of this 64 bit capability. Windows 7 X64 can run X86, 32 bit software along with 64 bit. The CPU must be 64bit to run a 64 bit OS.

I have both the x32 and the x64 version on my computer

Quote : Additional Information:
Windows 7 retail edition will come with 2 install DVDs, a x32 and x64. You can install EITHER version on your computer, but not BOTH. The retail key you received will work with both versions, but is only authorized for one install at a time.Unquote

My Dell Studio 1535 came with Vista and x32. When I tried to instal Windows 7 x64, it did not work so I had to use the x32 version.

When my computer came back from a repair shop, it had the x64 installed! When I had to reformat myself (another problem) I used the x64 version CD, succesfully.

Yes, I have both the x32 and the x64 versions. But when I use the x64 version, Adobe Reader or Flash Player does not work (I cannot see a picture/crossword puzzle). I have to then use the x32 version.

Should I just de-install the x64 version and install the x32 version with my CD?

TIA,

Guy

I'm running Windows 7 x64 Home Premium, and have Adobe Reader and Flash Player working flawlessly. Rather than do a complete reinstall, first try updating Reader and Player at http://www.adobe.com/downloads/ If you need help with that, let us know.

What is x32?
</sarcasm>

Quick Info:

There is no "x32" term to define "32 bit"-ness. The CORRECT term is x86, x64 comes for x86-64 in "shortened version". The basic instruction set is still x86 ISA. Why do they call it x86? Because the ISA was used in Intel's 8086, 80286, 80386, 80486 (starting to notice many "86"s?), 80586 (a.k.a Intel Pentium), 80686 (a.k.a Intel Pentium 2 and it's derivatives) - thus the term x86.

Where did x64 comes from? It comes from x86-64, meaning it's an x86 ISA with 64bit extension instruction set (made by AMD). The basic still stands, x86 instruction set to define the "standard" 32bit ISA, and x86-64 (or x64 in short) to define x86 ISA WITH 64bit extension instruction set.

We must use the correct terms in discussions...
